durian （Durio zibethinus Rumph. ex Murray） is an exotic tropical fruit known for its excellent flavor and strong distinctive aroma. Volatiles of durian pulp from different cultivars in Thailand, Malaysia and Indonesia were already reported. However, no study of volatiles from Philippine ＂Puyat＂ durian is available. ＂Puyat＂ is the most preferred by consumers in the Philippines due to its firm flesh with sweet and buttery taste. Aroma volatile compounds were analyzed by headspace solid phase microextraction （HS-SPME） method and gas chromatography-mass spectrometry （GC-MS）. Volatiles were extracted for 1 h using 65 μm PDM/DVB SPME fiber and separated by DB-WAX capillary column （30 m × 0.25 mm id × 0.25 μm film thickness）. durian pulp produced 22 volatiles composed of 15 esters, six sulfurs and one thioacetal. Ethyl propanoate, ethyl octanoate, propyl propanoate, ethyl 2-methyl butanoate and diethyl disulfide were the major compounds identified. These compounds were also reported to be the most abundant in durian cultivars of other countries. Results of this study can then be used for future development of postharvest technologies to control the production of volatiles from Philippine durian pulp.

Removal of Cu(II), Pb(II) and Zn(II) Ions from Aqueous Solutions Using Selected Agricultural Wastes: Adsorption and Characterisation Studies

The feasibility of durian tree sawdust (DTS), coconut coir (CC) and oil palm empty fruit bunch (EFB) as low-cost biosorbents for the removal of Cu(II), Pb(II) and Zn(II) ions from aqueous solutions was investigated. The effects of solution pH and initial metal concentration on adsorption capacity were examined in batch experiments. The affinity and the adsorption capacity of DTS, CC and EFB were evaluated. The adsorption behaviour of Cu(II), Pb(II) and Zn(II) ions onto DTS, CC and EFB was described using Freundlich and Langmuir isotherm models. The separation factor (RL) analysis suggests that the removal of metal ions onto three agricultural wastes studied was favourable. The maximum adsorption capacities (Q) estimated from the Langmuir isotherm model for Cu(II), Pb(II) and Zn(II) were 18.42, 20.37 and 22.78 mg/g for DTS, 18.38, 37.04 and 24.39 mg/g for CC, and 26.95, 37.59 and 21.19 mg/g for EFB, respectively. The characterisation studies were carried out using Scanning Electron Microscope (SEM), Energy Dispersive X-ray Spectrometer (EDX) and Fourier Transform Infrared Spectrometer (FTIR). The surface morphology of the biosorbents changed significantly following interaction with metal ions. The primary adsorption mechanism was complexation between metal ions and binding sites of biosorbents. Both hydroxyl and amine groups are the main binding sites in DTS, CC and EFB.
